SH EET-METAL CAN.

SPECIFICATION forming part of Letters Patent No. 234,269, dated November 9, 1880.

Application filed July 1, 1880.

To all whom it may concern Be it known that I, CHARLES GREEN, of Greenville, Delaware, have invented an Improvement in Sheet-Metal Cans, of which the following is a specification.

My invention relates, generally, to hermetically-sealed cans-or vessels for the inclosing of paints, preserved edibles, powder, solids, and liquids generally.

My invention relates more specifically to an improvement in the construction of sheet-iron and tin cans and vessels, by which I am enabled to use an inferior quality of metal to form the body of the can or vessel, and at the same time render it strong and durable at the seams and other portions most exposed to wear.

In practice the seams and corners of cans require to be stronger than the sides or other flat surfaces, for the reason that the corners and seams receive the greatest strain and are the most subjected to wear.

Of the drawings, Figure 1 is a central sectional elevation of a portion of a can embodying my invention, and representing the lapjoint by which the cover is secured to the side body formed with a double thickness of side body and strengthening-band. Fig. 2 is a similar View, the seam containing but a single thickness of side body. In both these views the strengthening-band is upon the outside of the side body. Fig. 3 is a view similar to Fig. 1, with the exception, however, that the strengthening-band is upon the inside of the side body. Figs. etand 5 are top sectional views through the portion of the can embraced by the strengthening-band, showing in Fig. 4 a construction by which the strengtheningband is riveted together and is not folded within the side seam of the side body, and in Fig. 5 a construction in which the strengtheningband isfolded with the side body to form conjointly with the same the side seam.

My invention consists in a sheet-metal vessel, to the ends of the side body of which are secured, upon either the inside or outside thereof, separate strengtheningbands of metal, preferably by means of beads or corrugations spun or otherwise formed into the metal of both bands and-side body, the bands extending beyond the termination of the side body (No model.)

and seamed with the metal of the heads to form the joints, securing the same in place.

It is of course clear that one head only of the can may be secured in the manner of my invention, a strengthening-band being applied to but one end of the side body, and the other head being secured in some well-known method. In practice it is immaterial whether the band be placed upon the inside or outside of the end of the side body, as it is equally possible to apply it in either way. The seaming may be either single or double.

The side body can be made of inferior metal in the practice of this invention; but the strengtheningband must be made of good metal, stronger and better adapted to be bent and to resist strains and wear than that of the side body.

In the drawings, A represents the side body of a can, B the strengthening-strip, and Cthe corrugation or head by which the latter is secured to the former. D is the top or bottom of the can.

In Fig.1 a double lap-joint is represented as securing in place the top, and in this joint both side body and band are lapped together.

In Fig. 2 a double lap-joint is represented, in which the band only is lapped with the metal of the cover, the side body stopping at the point marked a.

In Fig. 3 the band is upon the inside, but the joint is otherwise similar to that of Fig. 1.

In Fig. 4. the side seam ot the side body is indicated by b, while the riveted joint of the band is indicated by c.

In Fig. 5 the side seam is formed into both band and side body, as indicated at d.

Such being the construction of my invention, it is obvious that the band is subjected to the most severe strains, as in the case of the joint of Fig. 2, and that therefore cheaper metal which could not be properly seamed can be employed to form the side body. It is obvious, also, that the application of the band forms a stronger vessel, and that it does not detract otherwise from its utility.

The band may, if desired, be applied to one end only, and more than one bead may be employed to effect the union of the band.

Havingthus described my invention,Iclaim and desire to secure by Letters Patent 01' the heads to form the joints which secure the lat- United Statester in place, substantially as described.
